Not yet, but I can imagine them adding those features in future generations.

The car does slow down when you hit a slower zone, too:

The second half of the course demos some of the car's new "autopilot" features. This isn't full control of the car. It's little things like letting you change lanes just by flicking your turn signal (while the car looks out for anything that may be around you), as well as identifying signs and people. Nobody jumped out at us, but the car automatically changed its speed when we hit a slower zone.
